Objective To explore the role of Beclin 1 and PTEN in gastric caicinoma genesis and the effects on prognosis.Methods The expression of Beclin 1 and PTEN in 199 gastric caicinoma specimens and corresponding adjacent noncancerous tissues were examined by tissue microarrays and immunohistochemistary,and the relation with gastric cancer was analyzed.The rate of Beclin 1 and PTEN expression in 15 fresh gastric carcinoma samples and corresponding adjacent noncancerous tissues were detected by Western blot.All the samples were from Changzheng Hospital.Results The Results of immunohistochemistary showed that the rates of Beclin 1 and PTEN positive expression in cancinoma tissues were 47.2％ (94/199) and 55.8％ (111/199),both were lower than that of adjacent noncancinoma tissues (94.5％,188/199 and 92.5％,184/199; P ＜ 0.01).The lower expression of Beclin 1 and PTEN in gastric carcinoma were associated with gender,differentiation degree,depth of tumor invasion,lymph node metastases and disease stage(P＜0.05).There was a positive correlation between Beclin 1 and PTEN expression in gastric carcinoma tissues (r =0.680,P＜0.01). The survival analysis indicated that Beclin 1 and PTEN were independent factors in determining the prognosis of gastric cancinoma patients.The 5-year survival rate of Beclin 1 positive patients was 67.0％ (63/94),and of negative patients was 33.3％ (35/105).The 5-year survival rate of PTEN positive patients was 71.2％ (79/111),and of negative patients was 21.6％ (19/88) ( all P＜0.001).The Results of Western blot indicated that the expression of Beclin 1 and PTEN in gastric carcinoma tissues were significantly lower than that in the adjacent noncarcinoma tissues ( all P＜0.001).Conclusion The abnormal expression of Beclin 1 and PTEN may be related to carcinogenesis and the development of gastric carcinoma.

Objective To explore the feasibility of coelocentesis in prenatal diagnosis.Methods Coelocentesis were applied on 58 women scheduled for at 6～12 weeks of gestation,and fetal heart rate before the procedure and 1,5,30 minutes afterwards and hemorrhage of amnionic cyst was observed.Y gene of sex-determining region was detected by polymerase chain reaction,and compared with chorionic villi sample.Results The total achievement ratio of coelocentesis was 96.6% of all cases in five minutes.The coelomic fluid was successfully aspirated at first attempt in 93.2% at 7～10 week's gestation,25.0% at 6～7weeks and 50.0% at 10 ~ 12 weeks.There was no significant difference in FHR between before coelocentesis and afterwards (P＞0.05).The detection accurate rate of SRY was 91.1%,all female fetus were matched with those observation by chorionic villi sampling,and only 5 male fetus were not matched,the accurate rate was 80.8%.Conclusion Coclocentesis has the advantage of simple procedure,safe and high feasibility.The optimal time of coclocentesis is in the 7th to 10th week of gestation.

Background As one of the most common microvascular complication of diabetes in eyes,diabetic retinopathy (DR) is one of the most important cause of blindness.Nuclear factor-kappa B (NF-κB) is involved in the occurrence and development of the disease through the activation of a series of inflammatory cytokines.Objective The present study was to investigate the effects of peroxisome proliferator-activated receptor-gamma (PPAR-γ) excitomotor,rosiglitazone,on NF-κB expression and apoptosis of the retinal ganglion cells (RGCs) in the retina with diabetes mellitus. Methods Ninety SPF male Wistar rats were randomized into normal control group,diabetic control group and rosiglitazone group.Diabetes mellitus was induced by intraperitoneal injection of 50 mg/kg streptozotocin(STZ).Then 3 mg/kg rosiglitazone was intragastricly administered once per day in the rosiglitazonegroup,and the same volume of saline solution was used at the same way in the normal control group and diabetic control group from 3 days after modeling.The rats were sacrificed and the eye cups specimen was made at 4,8 and 12 weeks after usage of drugs.Retinal histopathological examination was performed by hematine-eosin staining,and expression of NF-κB p65 protein in retina and apoptotic index(AI) of RGCs were detected by immunohistochemistry and TUNEL assay,respectively in different time points mentioned above.The use of the animals complied with the Regulations for the Administration of Affairs Concerning Experimental Animals by State and Technology Commission.Results The blood glucose level was significantly elevated at various time points in the diabetic control group and rosiglitazone group compared with normal control group (P＜0.01 ),and that of the rosiglitazone group was significantly declined in comparison to the diabetic control group (q =0.81,0.82,1.23,P＞ 0.05 ).Normal retinal structure was seen in the normal control group,and edema retinal cell and disorder of retinal layers were exhibited in the diabetic control group.Retinal structure was almost normal in the rosiglitazone group.The NF-κB p65 was expressed weakly in the retina of normal control group,but the expression of NF-κB p65 was significantly elevated in the diabetic control group and rosiglitazone group compared with the normal control group(P＜0.01 ).However,the expression of NF-κB p65(A value)was significantly decreased in the rosiglitazone group compared with diabetic control group at 8 weeks and 12 weeks( q=17.77,15.30,P＜0.01 ).There were a few apoptotic cells in rat retina of the normal control group.Compared with the normal control group,the AI of the diabetic control group and rosiglitazone group was significantly reduced(P＜0.01 ).However,the AI of RGCs in the rosiglitazone group was significantly lower than that of diabetic control group in various time points (q =19.28,27.39,49.92,P＜0.01 ). Conclusions As one of the PPAR-γexcitomotors,rosiglitazone can inhibit apoptosis of RGCs through downregulating the expression of NF-κB in rat retina with diabetes mellitus,indicating a protective effect of rosiglitazone on retina in diabetic rat.
